Objective: To track the health-related quality of life (HRQL) at discharge and at 6 and 12 months after a traumatic brain injury (TBI) and examine factors associated with changes in each HRQL domain. Design: Longitudinal cohort study. Setting: Using codes of the International Classification of Diseases, eligible participants who had a newly diagnosed TBI were identified from discharge records of 4 hospitals in northern Taiwan. Information on the HRQL and injury-related characteristics at the initial and 2 follow-up assessments was collected by extracting medical records and conducting telephone interviews. Participants: Subjects (N=158) participated in the initial assessment, and 147 and 146, respectively, completed the follow-up assessments at 6 and 12 months after injury. Interventions: Not applicable. Main Outcome Measure: The brief version of the World Health Organization Quality of Life (WHOQOL-BREF) with 4 domains of physical capacity, psychologic well being, social relationships, and environment. Results: Scores on all WHOQOL-BREF domains except social relationships greatly improved over the first 6 months and showed continued improvement at 12 months after injury. The domain scores of the WHOQOL-BREF at discharge were significantly associated with the preinjury HRQL level, marital status, alcohol consumption at the time of injury, Glasgow Outcome Scale (GOS) level, cognition, activities of daily living, social support, and depressive status. However, after adjusting for these baseline differences, only the GOS level and depressive status significantly influenced longitudinal changes in the psychologic and social domains over the 12-month period. Changes in the physical and environmental domains were not significantly associated with any characteristics of the study. Conclusions: During the first year after a TBI, the magnitude of HRQL recovery differed across different HRQL domains. Many factors may have significant associations with the initial domain scores of HRQL after TBI; however, only a few factors can significantly influence longitudinal changes in the HRQL.
